COOLING-LIQUID EGONOMLIZER.

of Indiana, have invented certain new and,

useful Improvements in Cooling-Liquid Economizers, of which the following. is a specification.

My invention relates to a cooling liquid economizer and is particularly applicable to such an economizer for rotary refmgerating machines.

Rotary refrigerating machines have been constructed heretofore of two chambers, one

of which contains a liquid, suchas sulfurous anhydrid, which has been compressed and which subsequently vaporizes in the other chamber, producing a' fall of temperature. The compressor end of such a machine becomes very hot unless some means are provided for keeping it at a proper temperature. In order to do this, it has been customary heretofore to. run the compressor end of such a machine in a cooling liquid which is constantly renewed and to pass cooling air over the liquid which is splashed by the revolution of the machine. The quantity of cooling liquid required with such an -arrangement is very great.

My invention has for its object a novel arrangement whereby the compressor end of a rotary refrigerating machine, or any revolving heated member, may'be kept at a proper temperature with a much smaller quantity of cooling liquid than was possible heretofore. To this end, according to my invention, the heated member-revolves in a tank containing liquid and splashes the liquid against a suitable device about the re-' volving member which breaks it up into particles, these particles being cooled by cooling air. In order to prevent the escape of any of the liquid with the cooling air, 1

preferably provide a bame member in the path of the cooling air. Other features of novelty which characterize my invention are pointed out with particularity in the claims annexed to and forming a part of this specification.

For a better understanding of my invention reference may be had to the following description taken in connection with the acco'mpanying drawing in which- Figure 1 is a side elevation, partly in section, of my economizer; F g. 2 is an 'end ele vation of the economizer of Fig. 1, and Fig. 8 1s a perspective view of a detail.

Referr ng to the drawing, 1 is a tank provided with a suitable inlet and outlet (not shown), andcontaining a cooling liquid 2.

d heated member 3, whichis shown as the compressor end ofsuch a rotary refrigerating machlne-as described above, is mounted to revolve in the tank 1. By its revolution the cooling liquid is splashed or sprayed by the member 3 against a sieve 4 which breaks up into particles the liquid which has been splashed. This sieve may be a wire screen, the size of the mesh of which is not material, except that it must not be too large. have found that a inch mesh is very satisfactory. A fan 5 is provided for Eorcmg cooling air about the particles of the splashed liquid, as will hereinafter ap pear.

In order. to prevent the escape of any of v the liquid with the cooling air, I preferably provide a baflle member 6 in the path of the cooling air. The sieve 4 is preferably mounted in a'casing 7. This casing 7 is shown as reaching down into the liquid 2, and as mounted on the tank 1 by means of brackets 8 and angle irons 9. The sieve 4 is supported in a casing but out of contact therewith, by means of angle irons 10. The casing has an opening 11 above the sieve and openings 12 near the bottom thereof. A pipe 13 connects the opening 11 in the casing with the fan 5. The battle member 6 is mounted in thispipe.

I have shown the fan 5 as being supported by means of a bracket 14 from the side of the casing 7. The fan may be driven from a shaft 15 through a belt 16. The members of'the refrigerating machine may also be driven from this shaft 15 by means of pulleys 17 and 18 and belt 19. The vbailie member is shown as being composed of three baffles 20, 21 and 22 stacked together at an angle of 45 degrees to each other, the center one being reversed in relation to the angle of the bafile lates. Each baffle is a unit composed of six bafiie plates set at an angle of 45 degrees to the horizontal or vertical axis. In other words, each of the bames composing the baffle member are exactly alike, and in order to make the baflie member 6, these units are all placed in line in the same direction and set one on to of the other with the axis of the bame p ates as at the same temperature w dis laced by 45' degrees, after which the mi dle baflle is reversed. The arrangementof the bafiie member 6 in the ipe 13 is such that the water strikes the be e 22 square on,

or normal to the face of the baflie plates, and

the last bafiie rectly to the an. By arranging the baiile member 6 in this way, the passage of 111015- ture therethrough is absolutely stopped,

10. while the air will pass therethrough unmterruptedly. Furthermore, the area of the orifice is not reduced'by my arrangement -of baffle plates.

The operation of my economlzer 1s as fol:

15 lows: When the heated member 3 revolves I q in the cooling liquid 2, it throws oil a large quantity thereof by centrifugal force. This liquid is thrown through'the sieve 4, partially surrounding the upper side of the I member 3'. While the water is thrown through this sieve by centrifugal force, currents of air produced by the fan 5 are forced over the sieve and also through it, thereby perfectly aerating the water. This effects a i considerable cooling of the cooling liquid and consequently reduces the amount of water required for condensing the gas'in the compressormember 3. I have found, that, with a machine making about 28 pounds of 5 30 ice per hour, it only requires 83/100 of a gallon of water an hour to keep the member 3 at the proper temperature with my econo- Imi'zer in operation, while-it requires 49 gallons of water an hour to kee the. member 3 en my economizer is not in operation.

[I desire it to be understood that my in- "vention is not limited to the particular arrangement shown and described, and I aim I 40 in the appended claims to cover all modifications w ich do not depart from the spirit and scope of my invention.
